People complain about his rebounding and defense, but look at Kyrie. Yes he's not a lock down defender, and he does get beat, but he's playing really solid D right now. Why? Stevens and his system. He gets guys to buy into it.
I don't think Okafor will become some kind of rebounding defensive monster over night or ever if he came here, but he can improve, and he's already gotten his body in better shape like Smart did, so the effort is there.
I's still only do it on the cheap, but this could be best case for Okafor if he does want to become a legit NBA player. Playing with Horford and Baynes would do wonders for the kid. I mean who's been mentoring him in Phili? You could see from day one he didn't want to be there, and it's shown on the court. But get him with a guy like Horford, who are similar in playing style where is more foot work than athletics(Horford is a slightly better athlete), he could be come a really solid player.
He played one game this year and played 22 min had 10 and 9 and had 2 blocks with it. I'd be fine with giving up a late first round pick to see if he can be consistent with number like that.
